TECHNICAL FIELD

The present disclosure relates to a display device and a method ofcontrolling the same. More particularly, the present disclosure relatesto a display device which controls a display of a window in which anapplication is executed, and a method of controlling the same.

BACKGROUND

A desktop computer has at least one display device (for example, amonitor). A mobile device (for example, a mobile phone, a smart phone,or a tablet PC) using a touch screen typically has one display device.

A user of the desktop computer may divide a screen of the display deviceaccording to a working environment (for example, horizontally orvertically divide the screen while displaying a plurality of windows).When a web browser is executed, the user can move in an up or downdirection of the web page by using a page up button or a page downbutton arranged in a keyboard. When the user uses a mouse instead of thekeyboard, the user can move in the up or down direction of the web pageby selecting a scroll bar located in a side part of the web page byusing a cursor. Further, the user can move in the up or down directionof the web page by selecting a top button displayed as a text or an iconlocated in a bottom part of the web page.

The mobile device has a smaller size of the displayed screen as comparedto the desktop computer and has a limitation in an input. It isaccordingly difficult for the user to divide the screen of the mobiledevice.

Further, the mobile device can execute various applications such asbasic applications produced by a manufacturer of the mobile device andthen installed in the mobile device and additional applicationsdownloaded from an application store through the Internet. Theadditional applications may be developed by general users and registeredin an application store. Accordingly, anyone can freely sellapplications to users of the mobile device through the applicationselling site. Accordingly, upwards of hundreds of thousands of free orpaid applications are provided to the current mobile devices accordingto types of mobile devices.

Although various applications which simulate consumers' curiosity andsatisfy consumers' demands are provided to the mobile device, since themobile device is provided to have a portable size, it has a limitationin a size and a User Interface (UI) thereof. Accordingly, the users feelinconvenience in executing a plurality of applications in the mobiledevice. For example, when one application is executed in the mobiledevice, the application is displayed in an entire display area. Further,when the user desires to execute another application, the user shouldfirst end the currently executed application and then select anexecution key for executing the desired application. In order to executeseveral applications in the mobile device, processes of executing andending the respective applications should be repeated, which iscumbersome. Further, a method of simultaneously executing the severalapplications in the mobile device has not been provided.

A mobile device of the related art does not define an execution spacedesignated for each application. Accordingly, in switching anapplication screen which is being executed to another applicationscreen, the conventional mobile device is required to end theapplication which is being executed, return to a home screen, and thenexecute another application in the home screen. Further, when sharingdata between applications, the conventional mobile device is required tocopy data from one application, return to a home screen, and thenexecute another application to paste the data.

The above information is presented as background information only toassist with an understanding of the present disclosure. No determinationhas been made, and no assertion is made, as to whether any of the abovemight be applicable as prior art with regard to the present disclosure.

TABLE 1 Sub space Range of an x axis Range of a y axis index coordinatevalue coordinate value 1 −300~0    300~600 2  0~300 300~600 3 300~600300~600 4 −300~0     0~300 5  0~300  0~300 6 300~600  0~300 7 −300~0   −300~0    8  0~300 −300~0    9 300~600 −300~0   

At least one window executing an application may be arranged within eachof the sub spaces 201 to 209. For example, a first window 210 executingan application B may be arranged in the second sub space 202. A secondwindow 211 executing an application G and a third window 212 executingan application H may be arranged in the fourth sub space 204. A fourthwindow 213 executing an application A may be arranged in the fifth subspace 205 through an entire screen. A fifth window 214 executing anapplication C and a sixth window 215 executing an application D may bearranged in left and right sides of the sixth sub space 206 in a splitmode, respectively. A seventh window 216 executing an application E andan eighth window 217 executing an application F may be arranged in upperand lower sides of the eighth sub space 207 in the split mode,respectively. The display device 100 may arrange at least one windowexecuting an application in each of the sub spaces 201 to 209.

The display device 100 may physically display one of the sub spaces 201to 209, for example, the fifth sub space 205 on the touch screen 190.The display device 100 may display, for example, the fourth window 213executing the application A of the fifth sub space 205.

The display device 100 may display another sub space based on an inputdisplay change gesture. For example, when a user inputs a rightward draggesture into the touch screen 190, the display device 100 may displaythe sixth sub space 206 on the touch screen 190. The controller 110 mayreset an x axis coordinate value of an area physically displayed on thetouch screen 190 to a value from 0 to 300 and a y axis coordinate valueto a value from 0 to 300, and also reset the remaining sub spacecoordinates based on the reset values. A configuration of changing andthen displaying the sub spaces is described below.

The controller 110 may manage each of the sub spaces 201 to 209 in theunit of pages. For example, when the user inputs the display changegesture from the fifth sub space 205 to the sixth sub space 206 asdescribed above, the controller 110 changes the displayed fifth subspace 205 into the sixth sub space 206 in the unit of sub spaces, (i.e.,in the unit of pages). The controller 110 may simultaneously display apart of the fifth sub space 205 and a part of the sixth sub space 206 toanimate the display change from the fifth sub space 205 to the sixth subspace 206 while changing the display, but does not display a mixed imageof the part of the fifth sub space 205 and the part of the sixth space206.

The controller 110 may manage each of the sub spaces 201 to 209 in theunit of pixels as opposed to pages. For example, when the user inputsthe display change gesture from the fifth sub space 205 to the sixth subspace 206, the controller 110 may change the displayed fifth sub space205 into the sixth sub space 206 in the unit of pixels. The controller110 may change a range of the x axis of the physically displayedcoordinate one by one such that the range is changed from (0, 300) to(1, 301), (2, 302), and so forth. As described above, the mixed image ofthe part of the fifth sub space 205 and the part of the sixth sub space206 may be displayed on the touch screen 190.

Although coordinates having a size of 900×900 are set with respect tothe entire application execution space 200, a coordinate value is set toa value from −300 to 600 with respect to the x axis, and a value frame−300 to 600 is set with respect to the y axis in FIG. 2A as an example,the coordinate value of the application execution space 200 can be setto another value. Further, in the application execution space 200according to the present disclosure, a size of each sub space, forexample, the page may be determined according to a size of the physicaldisplay area, for example, the touch screen 190.

FIG. 2B illustrates a case where a size of a physical display area of anapplication execution space according to another embodiment of thepresent disclosure is 1024×640.

Referring to FIG. 2B, one page may have a maximum size of 1024×640 asindicated by a reference numeral 250. At least one page is included in +and − directions of the x axis based on (0, 0), and at least one page isincluded in + and − directions of the y axis. Although FIG. 2Billustrates a maximum page size of 1024×640 as an example, a size of theapplication execution window may be larger or smaller according to asize of the display area. The size of the page has no limitation as longas it does not exceed a maximum size, and at least one applicationexecution window may be arranged on each page.

FIG. 3 illustrates a home execution space and an application executionspace according to an embodiment of the present disclosure.

Referring to FIG. 3, the terminal 100 may define the home executionspace 300 and the application execution space 200 as divided areasseparated from each other. For example, the terminal 100 may set acoordinate with respect to the application execution space 200 by usinga virtual space. As described in FIGS. 2A and 2B, the terminal 100 mayset the coordinate having a predetermined size with respect to theapplication execution space 200, and a coordinate value (x, y) thereofmay be set to be separated from the home execution space 300.

The home execution space 300 may be a space where a launcher related tothe home screen of the terminal 100 is executed and a launcher screen310 according to the execution of the launcher is generated. Thelauncher refers to an application associated with the home screen andcorresponds to a home application different from a general application.For example, when the terminal 100 is turned on, the launcher may beexecuted in the home execution space 300 and the launcher screen 310 bythe launcher is generated to be displayed on the touch screen 190. Forexample, the launcher screen 310 may include a home screen, and adesktop (background screen), a tray including shortcut icons forexecuting frequently used applications, various menus, or a thumbnailimage of an executable application may be displayed on the home screen.The home execution space 300 may be defined as one logical space anddisplayed by a plurality of views 301 to 304 according to a size of thephysical display area, (i.e., the touch screen) as necessary.

The application execution space 200 is a space where an application isexecuted and an application execution window according to the executionof the application is generated. The application may include a gameapplication, a video reproduction application, a map application, a memoapplication, a broadcasting application, a sports support application, apayment application, a picture editing application and the like, but theapplication according to present disclosure is not limited thereto.

The application execution space 200 may include a plurality of subspaces, for example, a plurality of pages 221 to 229 which canindependently execute a plurality of applications App #01 to App # n orexecute two or more applications, and the pages may be added or deletedin the application execution space 200. A size of each of the pages maybe the same as the size of the display area, that is, the touch screen190. Each of the plurality of pages 221 to 229 may display oneapplication execution window or two or more application executionwindows, (i.e., a multi window). As illustrated in FIG. 3, threeapplication execution windows 221-1, 221-2, and 222-3 may be displayedon one page 221, two application execution windows 222-1 and 222-3 maybe displayed on one page 222, and one application execution window 223-1may be displayed on one page 223. The application execution space 200may include the desktop (background screen) like the home executionspace 300 or the desktop may be set according to a selection by theuser.

According to an embodiment of the present disclosure, the terminal 100can display switching between pages in the application execution space200, switching between views in the home execution space 300, andswitching from a page of the application execution space 200 to a viewof the home execution space 300.

According to an embodiment of the present disclosure, the controller 110may include a framework to process the application execution space 200and the home execution space 300.

FIG. 4 illustrates a concept describing an application frameworkaccording to the present disclosure.

Referring to FIG. 4, an application framework 400 processes theapplication execution space 200 and the home execution space 300according to a corresponding event based on an event input by the user.The application framework 400 may include an event handler 410, anapplication manager module 420, and a window manager module 430.

When the user inputs a display change event in the application executionspace 200, the event handler 410 detects the corresponding displaychange event. For example, when the display change event is forscrolling a screen, the event handler 410 may generate a space movingevent by a scrolled delta and transmit the generated space moving eventto the application manager module 420. The application manager module420 serves as an interface for transmitting information transmitted fromthe application to the window manager module 430. For example, when theuser inputs a predetermined user gesture, such as a flick in anapplication mode, the application manger module 420 transmits movementlength information for moving the application by a movement lengthcorresponding to the input flick to the window manager module 430.

The application manager module 420 may directly approach the windowmanager module 430 to transmit data received from the application and toreceive a result thereof from the application. For example, theapplication manager module 420 transmits movement length informationreceived from the event handler 410 to the window manager module 430 toindicate that the application has been moved, and allows the windowmanager module 430 to move the application by a movement length.

The window manager module 430 corresponds to an object managinginformation on a position to which the application has been moved, whichmanages a page and information on a position where each application isexecuted.

A display operation using the home execution space 300 and theapplication execution space 200 can be performed through the abovedescribed application framework 400.

FIG. 5A is a diagram describing a method of executing an application ina home execution space according to an embodiment of the presentdisclosure, and FIG. 5B is a flowchart illustrating a process ofexecuting an application in a home execution space according to anembodiment of the present disclosure.

Referring to FIGS. 5A and 5B, the display device 100 determines whetheran application execution event by the user is generated in a state wherethe launcher screen 310 using the home execution space 300 is displayedin operation 5510.

The display device 100 may execute the application according to thegeneration of the application execution event by the user in the statewhere the launcher screen 310 using the home execution space 300 isdisplayed. The launcher screen 310 may have one view corresponding to asize of the touch screen 190 or may be divided into a plurality of viewsL1, L2, and L3 when the launcher screen 310 is larger than the touchscreen 190. Only one view L1 of the plurality of views may be displayedon the touch screen 190.

The user may generate the application execution event by using an iconfor executing the application in the view L1 of the launcher screen 130,by selecting the application from recently executed application lists(Recent apps), or by selecting the application from a predeterminedtray.

When the application execution event is generated in the home executionspace 300, the display device 100 executes the corresponding applicationA1 in the application execution space 200 in operation 5520. The displaydevice 100 generates and displays a page 260 including an applicationexecution window 262 in the application execution space 200 in operation5530.

FIGS. 6A and 6B illustrate a process of executing an application in alauncher screen according to an embodiment of the present disclosure.

Referring to FIG. 6A, when an icon 602 corresponding to the applicationwhich is desired to be executed by the user is touched on the launcherscreen 310 generated and displayed using the home execution space 300,the corresponding application is executed in the application executionspace 200 and thus the page 260 including the application executionwindow 262 may be generated.

Referring to FIG. 6B, when an icon corresponding to the applicationwhich is desired to be executed by the user is selected from thelauncher screen 310 generated and displayed using the home executionspace 300 and then dragged in a predetermined direction (for example, atop, bottom, left, or right direction), the corresponding application isexecuted in the application execution space 200 and thus the page 260including the application execution window 262 may be generated. Anembodiment of the present disclosure illustrates a case where, when theicon 604 is touched and then dragged in a top direction, thecorresponding application is executed in a space corresponding to thetop direction of the application execution space 200.

In a recent application list 312, recently executed applications arearranged in an execution order or pages generated according to therecently executed applications are sequentially arranged.

FIG. 7 illustrates an example of sequentially arranging recent pagesaccording to an embodiment of the present disclosure.

Referring to FIG. 7, each page includes an application name and athumbnail of one or a plurality of executed application executionwindows. A recently executed application list includes a page 701including a name 701-1 and a thumbnail 701-2 of a calculator applicationexecution window, a page 702 including names 702-1 and 702-3 andthumbnails 702-2 and 702-4 of a video player application executionwindow, and a page 703 including a name 703-1 and a thumbnail 703-2 ofan S note application execution window.

In the application execution window of each page, the application name,a border or underline displayed together with the application name, andthe thumbnail may be displayed with different sizes, different colors,or different display schemes in order to distinguish whether theapplication execution window is in a resumed state or paused state. Forexample, a name of the application in the resumed state may be displayedwith a first color, and a name of the application in the paused statemay be displayed with a second color. The name or a border of thethumbnail of the application in the resumed state may be displayed withthe first color, and the name or a border of the thumbnail of theapplication in the paused state may be displayed with the second color.For example, in FIG. 7, the application names 702-1 and 702-3 in thepage 702 are displayed differently from the names 701-1 and 703-1 of theapplication windows in the paused state in the pages 701 and 703 inorder to distinguish the page including the application window which isbeing executed from the pages in the paused state.

When the thumbnail of the application in the resumed state is selectedthrough a touch input by the user, a page including a correspondingapplication execution window is generated and displayed by using theapplication execution space 200. When the thumbnail of the applicationin the paused state is selected through a touch input by the user, a newpage is generated by using the application execution space 200 and acorresponding application execution window is included in the generatedpage. At this time, the paused state in the recent application list 312is changed into the resumed state.

For example, referring to FIG. 7, when the thumbnail 702-2 of thegallery application execution window included in the page 702 is touchedby the user, the page 260 including the corresponding galleryapplication execution window 262 is generated and displayed by using theapplication execution space 200. At this time, the video playerapplication execution window 264 included also in the page 260 may bedisplayed together.

Meanwhile, pages included in the recent application list 312 may bedisplayed after a movement according to a scroll request of the user.The scroll request may be made by a left or right drag input, or an upor down drag input. An embodiment of the present disclosure describes acase where the recent application list 312 moves according to the leftor right drag input.

Specifically, when the user touches and then drags a screen in a leftdirection in FIG. 7, the recent application list 312 is moved in theleft direction, the page located in a left side disappears, and a nextpage 704 located in a right side appears as illustrated in FIG. 7. Whenthe user touches and then drags a screen in a right direction in FIG. 7,the recent application list 312 is moved in the right direction, thepage 703 located in a right side disappears, and a previous page 705located in a left side appears.

Accordingly, the user can easily identify and control the pages of theapplication execution space 200 even in the home execution space 300 byusing the recent application list 312.

FIGS. 8A to 8D illustrate a process of executing an application from atray according to an embodiment of the present disclosure.

Referring to FIG. 8A, a display device 800 displays a first window 801executing a first application A. The display device 800 may display atray call button 810 at a left center of the first window 801. The traycall button 810 has a semicircle shape. When the tray call button 810 istouched, the tray opens in a right direction, which matches a users'intuition. However, it may be easily understood by those skilled in theart that the tray call button 810 may have any shape. The user can callthe tray by touching the tray call button 810 or inputting a draggesture 811 in a right direction. Since the tray call button 810 callsthe application list, the tray call button 810 may be more generallynamed an application list call button.

FIG. 8B illustrates a called tray. In response to a tray call commandsuch as the touch or drag of the tray call button, a controller (notshown) controls to display a tray 820 displaying a list of executableapplications. The controller (not shown) controls to display thumbnailimages 821, 822, 823, and 824 of the executable applications on the tray820. The controller (not shown) may control to display all applicationsstored in a storage unit (not shown) on the tray 820. Alternatively, thecontroller (not shown) may identify attributes of the stored applicationand control to display an application which can operate in a multiwindow mode on the tray 820. The tray 820 also may be more generallynamed an application list.

After touching an application desired to be executed, for example, afifth application E, the user may input a drag gesture 830 toward anarea 835 in which the user desires to execute the application. Referringto FIG. 8C, when the user inputs the drag gesture 830 toward the area835 in which the user desires to execute the application, the controller(not shown) changes a color or brightness of the area in which theapplication can be executed. Accordingly, the user may identify a shapeof the window to be executed in the area 835 in which the user desiresto execute the application before a final execution of the application,which may be named a ghost-view.

The user may stop the drag input 830 in the area 835 in which the userdesires to execute the application. The gesture may be named a drag anddrop. When the area 835 in which the user desires to execute theapplication is determined, the display device 800 reduces a first window841 executing the first application A and displays the reduced firstwindow 841 on the upper half of an entire screen, and displays a fifthwindow 842 executing the fifth application E on the lower half. Asdescribed above, displaying the two windows 841 and 842 not to overlapeach other may be named a split mode, which will be described below inmore detail.

FIGS. 9A and 9B illustrate a freestyle mode and a split mode accordingto an embodiment of the present disclosure.

Referring to FIG. 9A, a display device 900 includes a touch screen 910.The touch screen 910 displays a plurality of windows 911 and 912. Alower bar 920 is displayed on a lower end of the touch screen 910. Asdescribed above, a display mode in which the plurality of windows 911and 912 overlap each other based on a display order of each window maybe named the freestyle mode.

The window may be an area including an execution screen of a particularapplication and a title bar and a control area of an executedapplication. Objects related to the application may be displayed on theapplication execution screen. The objects may have various shapes, suchas text, a symbol, an icon, a button, a checkbox, a picture, a video, aweb, a map, and the like. When the user touches the object, a functionor an event predetermined for the object may be executed in acorresponding application. The object may be called a view according toan operating system. The title bar may include at least one control keyfor controlling a display of the window. For example, the control keymay be a window display minimizing button, a window display maximizingbutton, or a window end button.

Applications are programs independently implemented by a manufacturer ofthe display device 900 or an application developer. Accordingly, apre-execution of one application is not required to execute anotherapplication. Further, although one application ends, another applicationcan be continuously executed.

The applications are distinguished from a complex function application(or dual application) generated by adding some functions (memo functionand message transmission/reception function) provided by anotherapplication to functions of one application in that the applications areindependently implemented programs. However, the complex functionapplication is a single application newly produced to have variousfunctions and thus has differences from conventional applications.Accordingly, the complex function application provides only limitedfunctions without providing various functions unlike the conventionalapplications. Further, users have the burden of separately purchasingsuch a new complex function application.

The controller 110 controls such that a plurality of windows 911 and 912are displayed to partially overlap each other. The controller 110 mayassign a display order to each of the windows 911 and 912. For example,the controller 110 may assign a first display order to the window 911and a second display order to the window 912. Accordingly, thecontroller 110 displays the window 911 having a relatively higherdisplay order to cover the window 912. A part of the window 912 having arelatively lower display order which overlaps the window 911 having therelatively higher order is not displayed.

The controller 110 may assign a highest display order to a window intowhich a control event has been most recently input. For example, whenthe user touches the window 911, the controller 110 assigns the highestdisplay order to the window 911.

FIG. 9B illustrates an example of displaying two applications on a maindisplay screen 910 in the split mode. When the user executes a pluralityof applications, a controller (not shown) may simultaneously execute theplurality of applications and display the applications on the mainscreen 910.

In the split mode, a first window 940 and a second window 950 may bedisplayed on the main screen 910 so as not to overlap each other. Forexample, as illustrated in FIG. 9B, when the main screen 910 is dividedinto two parts, the first window 940 may be displayed on the left halfof the main screen 910 and the second window 950 may be displayed on theright half of the main screen 910. Although the first window 940 and thesecond window 950 are arranged close to each other while sharing acommon boundary 970, they do not overlap each other. The common boundary970 is located between the first window 940 and the second window 950.

FIGS. 10A and 10B illustrate executing a plurality of applicationsthrough a touch input by the user according to an embodiment of thepresent disclosure.

FIG. 10A illustrates an embodiment of the present disclosure in which aplurality of applications are executed by a touch input of the user inthe freestyle mode.

Referring to FIG. 10A, the display device 100 may display a plurality ofapplication icons a1 to a9 and a tray 820 including a list of executableapplications a10 to a13 on the launcher screen 310 by using the homeexecution space 300.

The display device 100 may execute the plurality of applications in thelauncher screen 310 or the tray 820 according to a touch input of theuser. As the user touches a plurality of applications, for example,first to third applications a3, a5, and a12, the display device 100 mayexecute each of the first to third applications a3, a5, and a12 in theapplication execution space 300. In the freestyle mode, the displaydevice 100 may display all of a plurality of application executionwindows, for example, all of first to third application executionwindows 1011, 1012, and 1013 in a first page 1010.

FIG. 10B illustrates an embodiment of the present disclosure in which aplurality of applications are executed by a touch input of the user inthe split mode.

Referring to FIG. 10B, in the split mode, the display device 100 mayexecute two application execution windows per page. When theapplications a3, a5, and a12 are sequentially executed, the first andsecond application execution windows 1011 and 1012 may be executedtogether in a first page 1010-1 and the third application executionwindow 1013 may be executed in a second page 1010-2.

The case where the plurality of applications are executed by the user'stouch input has been described in FIGS. 10A and 10B. According toanother embodiment of the present disclosure, a plurality ofapplications may be executed according to a drag and drop input by theuser.

FIGS. 11A and 11B illustrate executing a plurality of applicationsaccording to a drag and drop input by the user according to anembodiment of the present disclosure.

Referring to FIG. 11A, an embodiment in which a plurality ofapplications are executed by a drag and drop input of the user in thefreestyle mode is illustrated. The display device 100 may display aplurality of application icons a1 to a9 and a tray 820 including a listof executable applications a10 to a13 on the launcher screen 310 byusing the home execution space 300. As the user drags and drops a fourthapplication a13 from the tray 820 to the application execution space 200while a plurality of applications, for example, the first to thirdapplications, a3, a5, and a12 are executed in a first page 1110 by usingthe application execution space 200, the display device 100 may executethe fourth application a13 in a second page 1120 of the applicationexecution space 300 to generate and display a fourth applicationexecution window 1121.

Referring to FIG. 11B, an embodiment in which a plurality ofapplications are executed by a drag and drop of the user in the splitmode is illustrated. While the first and second applications a3 and a5are executed in a first page 1130 by using the application executionspace 200, the third application a13 of the tray 820 is dragged anddropped to the application execution space 200 by the user. Accordingly,the third application a13 is executed in a second page 1140 of theapplication execution space 300 instead of the first application a3, anda second application execution window 1142 and a third applicationexecution window 1143 may be generated and displayed.

As described above, while the application is executed in the applicationexecution space 200 and the page including the corresponding applicationexecution window is generated, a mutual switching display between thepage including the application execution window and the launcher screen310 of the home execution space 300 becomes possible.

FIGS. 12A to 12C illustrate mutual switching between a launcher screenof a home execution space and a page of an application execution spaceaccording to an embodiment of the present disclosure.

Referring to FIGS. 12A to 12C, the display device 100 executes alauncher L having first to third views L1, L2, and L3 by using the homeexecution space 300 and executes first to fourth applications A1, A2,A3, and A4 by using the application execution space 200. The firstapplication A is executed in a first page P1, the second and thirdapplications are executed in a second page P2, and the fourthapplication A4 is executed in a third page.

The display device 100 displays the first view L1 of the launcher L ofthe home execution space 300 on the touch screen 190 as illustrated inFIG. 12A, and then may switch the displayed first view L1 to the firstpage P1 of the application execution space 200 and display the switchedfirst page P1 on the touch screen 190 according to generation of adisplay change event as illustrated in FIG. 12B. The display device 100displays the first page P1 of the application execution space 200 on thetouch screen 190 as illustrated in FIG. 12B, and then may switch thedisplayed first page P1 to the first view L1 of the launcher L of thehome execution space 300 and display the switched first view L1 on thetouch screen 190 according to generation of a display change event asillustrated in FIG. 12C. The display change event may be generatedaccording to a gesture input by the user.

FIGS. 13A and 13B illustrate cases where a display change event isgenerated by a gesture input according to an embodiment of the presentdisclosure.

FIG. 13A illustrate a case where a display change event is generated bya flick of the user according to an embodiment of the presentdisclosure. Referring to FIG. 13A, as a gesture of flicking the firstview L1 of the home screen in a bottom direction is input, the firstpage P1 of the application execution space may be displayed. Thisenables the user to recognize a concept that the application executionspace exists in a higher level of the home screen, which matches auser's intuition. A widget displayed on an upper part of the first viewL1 may be also displayed on a lower part of the first page P1 of theapplication execution space in (b) of FIG. 13A, but the widget may notbe displayed in (c) of FIG. 13A. An animation effect may be created inwhich the first view L1 is switched to the first page P1.

FIG. 13B illustrate a case where a multi touch, for example, a 3-touchgesture input is used. Referring to (a) of FIG. 13B, as a gesture ofmulti-touching and then dragging the first view L1 of the home screen ina bottom direction is input, only the first page P1 of the applicationexecution space may be displayed as illustrated in (b) and (c) of FIG.13B. The same performance as that in (a) of FIG. 13A is executed in (b)and (c) of FIG. 13B, thereby creating the animation effect. In responseto a gesture of multi-touching and then dragging the first page P1 ofthe application execution space in a top direction is input, the firstview L1 of the home screen may be displayed as illustrated in (d) and(e) FIG. 13B.
